             Summary: EAP 6.4 has threadlock appears related to logging
                 Key: JBLOGGING-117
                 URL: https://issues.jboss.org/browse/JBLOGGING-117
             Project: JBoss Logging
          Issue Type: Bug
         Environment: development environment- linux
            Reporter: Bill Rodriguez
            Assignee: James Perkins
            Priority: Critical


After our WAR starts up -- we have a 5 minute web services running and some JUI portal calls to the WAR which uses System.out.println and slf4j logger.  About 5-15 after start, the app no longer processes and the web serv seems to time out trying to obtain threads-

We capture a thread dump(attached) and it appears the bug is same bug as we saw in eap6.3-- we moved to 6.4 due to a post that said the bug had been fixed in 6.4 here:

http://stackoverflow.com/questions/30099371/jboss-eap-6-3-threads-get-deadlock-with-log4j-consoleappender

the above bug reference ConsoleAppender and our threaddump shows this class here:

"http-/10.19.80.121:9080-6":
  waiting to lock monitor 0x00007ff93406cbf8 (object 0x00000000c92a9230, a org.apache.log4j.ConsoleAppender),

It appears this bug is still present in 6.4-- and we are DEAD at the moment...
